The electrical conductivity of a solution is the measure of the solution's ability to allow current to pass through it. This property is attributed to the amount of ions that are present in the solution. So, the answer to this item is IONS which are the positively or negatively charged particles.
Molar solubility<span> is the number of moles of a substance (the solute) that can be dissolved per liter of solution before the solution becomes saturated. We calculate as follows:
</span>3Cu2+ + 2(AsO4)3-<span> = Cu3(AsO4)2 </span> 7.6 x 10^-36 = (3x^3)(2x^2) x = 6.62 x 10^-8 M
